A LASER APPARATUS

摘要

A laser apparatus comprising a laser means for directing a light beam through a first nozzle towards a workpiece (3) to be machined, said nozzle having an orifice (4), through which the light beam and a first gas jet may pass. Furthermore, the nozzle has a further orifice (5) for a further gas jet. Both orifices (4, 5) are provided with gas from the same chamber (7) and so closely interspaced that the flows merge. As a result, an increased machining quality is achieved due to the fact that the flows of closely interspaced orifices merge so that interfering gasses are not able to reach the area of machining.
